JAMES B. RYAN, OF NEW` YORK, N. Y., ASSIGNOR TO THE NEW YORK VOVEN VIREMATTRESS COMPANY, OF SAME PLACE.

BED-BOTTOM.

SPECIFICATION forming part of Letters Patent No. 599,739, dated March 1,1898.

Application led July 21, 1897. Serial No. 645,397. (No model.) v

To @ZZ whom, t may concern:

Be it known that I, J AMES B. RYAN, a citizen of the United States,residing at New York, in the county of New York and State of New York,have invented certain 'new anduseful Improvements in Bed-Bottoms; and Ido declare the following to be a full, clear, and exact description ofthe invention,such as will enable others skilled in the art to which itappertains to make and use the same.

My invention relates to that class of bedbottoms which embody woven wiremat# tresses; and it contemplates providing such a bed-bottom withcheap, simple, and efficient means for imparting extra strength to andholding the mattress under tension, so as to prevent undue sagging ofthe same at the center.

The invention will be fully understood from the following descriptionand claims when taken in conjunction with the annexed drawn, ings, inwhich- Figure l is a plan View of a bed-bottom embodyin g my inventionwith the mattress partly broken away. Fig. 2 is a detail transversesection taken in the plane indicated by the line x of Fig. l. Figs. 3and 4t are detail plan views of modifications, and Fig. 5 is a detailplan view of a modification with the mattres partly broken away.

. Referring by letter to the said drawings, and more particularly toFigs. l and 2 thereof, A indicates the frame of the bed-bottom, which ispreferably of the ordinaryrectangnlar form and construction.

B indicates the mattress of woven-wire fabric, which is also of theordinary construction and is connected to thefend bars a of the frame,and O indicates resilient rods, which are preferably of wire,as shown.These rods C are disposed transverse of the bed-bottom at opposite sidesof the middle thereof, and they extend through the meshes of the wiremattress and are thereby secured to the same, as illustrated. To-theserods C, I connect the ends of one or more (preferably three) helicalsprings D, which are disposed longitudinally below thefabricand betweenthe said rods O, and are preferably provided with hooks b lto permit oftheir ready connection to the latter. These springs D are stretched andlplaced in engagement with the transverse rods C under tension, and inconsequence it will be observed that they will hold the fabric B undertension and increase the strength and rigidity of the same, so as toprevent the undue sagging at the center, which is the common obj ectionto woven-wire mattresses. The

said springs D increase the tension of the mat- I prefer to employ therods C, because they materially increase the efficiency of the springsD. `I do not desire, however, to be understood as confining myself tothe same, as the springs may be connected with the mattress throughthe'medium of rings O', (see Fig. 3,) or their hook ends b may be placedin direct engagement with the wire of the mattress, as illustrated inFig. 4L.

In Fig. 5 of the drawings I have illustrated a modification in which amiddle transverse bar E is disposed transversely below the mattress B,free from connection therewith at its ends, and two transverse series oflongitudinally-disposed springs D are employed, said springs beinginterposed between the middle bar E and rods C and connected at theirends to the same, as shown.y

While this construction operates to further distribute the weight of aperson lying on the mattress upon the several springs and to strengthenand prevent undue sagging of the mattress, yet the construction shown inFig.

lis preferred because of its simplicity and cheapness. It will beappreciated from the foregoing that all of the embodiments of myinvention are exceedingly cheap and simple and are adapted to be quicklyand easily applied to a mattress. It will also be observed that themattress may be placed under more or less tension and thereby renderedmore or less stiffer rigid by stretching the springs to a greater orless extent prior to connecting their ends with the mattress.

Having thus described my invention, what I claim isl. A bed-bottomcomprising a frame, a mattress of woven-wire fabric attached to theframe, and one `or more horizontal, helical springs arranged below andparallel to the mattress; the said springs having their ends connectedtothe fabric forming the mattress at intermediate points in the length ofthe same, and being stretched or under tension, whereby they aresupported by the mattress and are adapted to prevent sagging of thesame, substantially as specied.

2. A bed-bottom comprisingaframe, a mattress of Woven-wire fabricattached to the same, and the transverse, resilient rods and a series ofhorizontal, helical springs carried by the fabric forming the mattress;the said rods being disposed at opposite sides of the middle of thebed-bottom and between said middle and the ends andthe springs heiligstretched or under tension and arranged below and parallel to themattress and extend ing in the direction of the length of the bedbottombetween the transverse rods and having their ends connected to saidrods, substantially as specified.

3. A bed-bottom comprising a frame, a woven-wire mattress or fabricattached to the frame, transverse resilient rods extending through themesh of the fabric and disposed at opposite sides of the middle of thebottom, a resilient transverse bar arranged between said rods and belowthe mattress or fabric, and transverse series of longitudinally-disposedsprings arranged below the mattress or fabric and connecting theresilient bar with the resilient rods, substantially as specified.

In testimony whereof I affix my signature in presence of two witnesses.

JAMES B. RYAN.
